Tribe of legumes
Thetribe Amorpheae is an early-branchingclade within theflowering plant subfamilyFaboideae or Papilionaceae. It is found fromMexico toArgentina .[ 2] It was recently found to belong in a larger clade known informally as thedalbergioids sensu lato .[ 2] [ 3] [ 4] This tribe is consistently resolved asmonophyletic inmolecular phylogenetic analyses .[ 2] [ 3] [ 4] [ 1] [ 5] [ 6] [ 7] [ 8] [ 9] [ 10] It is estimated to have arisen 36.9 ± 3.0 million years ago (in theEocene ).[ 6] A node-based definition for Amorpheae is: "theMRCA ofPsorothamnus arborescens andEysenhardtia orthocarpa ."[ 6] The tribe exhibits the following morphologicalsynapomorphies : "epidermal glands throughout the plant body; dry, indehiscent fruits that are single-seeded; and terminal inflorescences."[ 1]
Subclades and genera [ edit ] The amorphoids can be distinguished from the daleoids on the basis of their non-papilionaceous flowers.[ 1]
The daleoids can be distinguished from the amorphoids on the basis of their generally papilionaceous corollas.[ 1]
